Filipendula purpurea, commonly known as Purple-stemmed Meadowsweet or Nineleaf Meadowsweet, is a perennial herb native to moist meadows, forest clearings, and riverbanks in Far East Russia, Mongolia, China, and Japan. It exhibits a moderate growth rate, reaching heights of 2-4 feet (0.6-1.2 meters) and spreading 2-3 feet (0.6-0.9 meters). This species is characterized by its deeply lobed leaves and striking purple stems, which contrast with the clusters of small, fragrant pink or white flowers that appear in the summer. The flowers are showy and attract pollinators, adding to the plant’s ornamental value.

Purple-stemmed Meadowsweet is valued for its ease of maintenance and its ability to thrive in a variety of soil types, including clay, loam, and sandy soils, provided they offer medium drainage. It prefers full sun to part shade and requires medium amounts of water, making it suitable for rain gardens and naturalized areas. It is often used in border plantings, cottage gardens, and as a component of pollinator-friendly landscapes. While generally disease-resistant, it can suffer from powdery mildew in humid conditions. It is not known to be invasive and does not have aggressive roots, making it a safe choice for most garden settings.CC BY-SA 4.0
